The non-Tcl ("standard") configuration links the bundled GNU readline,
and that path was broken two ways:
* headers: readline's own headers use <readline/*.h> includes, so the
readline source's parent must be on the include path. Nothing added
it, so every module including readline (commands, textio, ...) failed
with "readline/rlstdc.h: No such file". Add -I${MAGICSRC}/readline to
CPPFLAGS for the bundled build only (@MAKE_READLINE@ = 1).
* library: readline/Makefile ran "../readline/configure" from the
build-readline dir -- a source-relative path that, out-of-tree, points
into the (empty) build tree. Use ${MAGICSRC}/readline/readline/
configure so the out-of-source readline build finds its sources.
Verified: `mkdir b; cd b; ../configure --without-tcl && make` now
completes (rc=0) and produces the native magic binary; previously it
died at commands/CmdFI.o (headers) then at the readline library build.

rename symlink(s) use phony targets, delegate the symlink creation
management command sequence to a single point in the project inside
the readline/Makefile
generally unused, as it is incompatible with the Tcl/Tk build of
magic. However, I had not intended to remove it, only move the
name from "readline-4.3" to "readline". But "readline/readline"
was in .gitignore, which caused the contents to be removed from
the repository. This commit restores those files, and also
prevents the readline directory Makefile from making a symbolic
link called "readline" to itself, which was causing compile-time
issues. The readline code is only kept for backwards compatibility
with ancient versions of magic not using the Tcl/Tk interpreter.
